I have an old Johnson (1963 5 HP, I think), model CD20C, S/N 2298226. Can someone tell me what the correct mixture should be for this motor?

Thanks ...

1963 is correct the fuel oil mix is 24 parts, 87 octane, to 1part, tcw3 outboard motor oil. the change to 50- 1 was for most motors, in 1964.

Those engines in the '60's used 24:1.....nice mosquito repellant.
